Breast-conserving surgery (BCS) is sometimes called a lumpectomy or a partial mastectomy. It may be done as part of a treatment plan for breast cancer. With BCS, only the part of the breast that has cancer is removed.
Lumpectomy is surgery to remove cancer. It's a breast-conserving surgery, which means your breast remains intact. If you're having a lumpectomy, you'll probably also have radiation therapy.
Surgery is often used to treat thymus tumors. Different kinds of surgery may be done. Which type you have depends on how much the cancer has spread, and other factors. Learn more.
